Describe Email usage at work

a) Electronic mail (email) refers to the process of using telephone and computers lines as a mailing system for both external (internet) and internal (intranet) communication purposes. 

b) Email could encourage unofficial communication in several ways, such as:

• Allows personal messages to be sent from the workplace to family and friends
• May not be supervised (by the employer) so this can encourage informal communication and emails not related to work
• There is no financial cost to the sender (employee) so this may further encourage informal communication, both externally and internally
